The HP 8015A is a 50 MHz pulse generator that features dual outputs - each capable of delivering pulses up to 16 V in amplitude. When the outputs are combined (A + B mode), up to 30 V is available.

The 8015A is easy to use - the front panel layout is clear and unambiguous. Controls are positioned so that parameters are easily identified and invalid combinations of parameters can be avoided.

Delay, double pulse, and square wave modes of operation are available. A feature of the 8015A is the B Del mode where channel B output is delayed with respect to channel A output. This can be combined with A + B mode so that complex and 3-level waveforms can be synthesized. The external input has a threshold level variable between +1 V and -1 V with 50 Ω input impedance and variable between +10 V and -10 V with 500 Ω input impedance. A push button permits manual simulation of input signals for all external modes of operation.

• Pulse transition times: Minimum to 0.5 s in four ranges
• Linearity: For transition times >30 ns, maximum deviation from a straight line between the 10% and 90% points is less than 5% of pulse amplitude
• Overshoot and ringing: ±5% of pulse amplitude, possibly increasing to <±10% at minimum amplitude
• Preshoot: <5% of pulse amplitude
• Pulse top perturbations: Droop <5% of pulse amplitude
• Pulse width: < 10 ns to 1 s in four ranges
• Width jitter: <0.1% + 50 ps
• Pulse delay: 20 ns (+25 ns fixed) to 1 s
• Delay jitter: <0.1 % + 50 ps 
• Modes of operation
  • Norm (internal): Pulse parameters are defined by the front panel controls - no external signal source is required 
  • Gate: An externally applied signal source enables and disables the internal repetition rate generator. Gating is synchronous; the first pulse is initiated by the start of the gate signal, and the last pulse is always complete even if the gate signal ends during generation. All pulse parameters, other than the duration of the gate, are defined by the front panel controls. A synchronous trigger output is available for the duration of the pulses 
  • Ext Trig: Pulse rate and trigger output frequency are defined by the frequency of an externally derived signal source. All other pulse parameters are varied by the front panel controls
  • Ext Width: Pulse rate and width are defined by the frequency and width of an applied signal. The frequency of the trigger output pulses can be varied independently of the pulse output frequency
• Repetition rate: 1 Hz to 50 MHz in four ranges
• Period jitter: <0.1% + 50 ps
• Square wave: 0.5 Hz to 25 MHz
• Double pulse: 25 MHz maximum (simulates 50 MHz)
• B delay: 20 MHz maximum
• Trigger pulse width: 9 ns ±5 ns
• Maximum internal input: ±7 V
• Trigger polarity: Positive or negative slope selectable
• External triggering repetition rate: 0 to 50 MHz
